  1. 16. Application of dynamic rating to improve transportation capability of the power systems connected to wind power plants

    Master-uppsats, KTH/Skolan för elektro- och systemteknik (EES)

    Författare :Marco Merante; [2016]
    Nyckelord :dynamic line rating; overhead lines; conductor temperature model; wind energy;

    Sammanfattning : Current flow in the electrical grid is changing due to the introduction of new generators and loads.Specifically, weak Overhead lines, are a constraint for the introduction of wind farms located farfrom the central network. The current situation requires smart solutions to improve the transportationcapabilities of these grid’s components. LÄS MER

    Sammanfattning : At present there are different reliability standards that are being used for carrying out reliability prediction. They take into consideration different factors, environments and data sources to give reliability data for a wide range of electronic components. LÄS MER

  4. 18. One-Dimensional Human Thermoregulatory Model of Fighter Pilots in Cockpit Environments

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Elias Nilsson; [2015]
    Nyckelord :human heat transfer; body temperature regulation; physiological model; cooling garment; cockpit modeling;

    Sammanfattning : During flight missions, fighter pilots are in general exposed to vast amounts of stress including mild hypoxia, vibrations, high accelerations, and thermal discomfort. It is interesting to predict potential risks with a certain mission or flight case due to these stresses to increase safety for fighter pilots. LÄS MER

  5. 19. Optimization of thermal response test equipment and evaluation tools

    Master-uppsats, KTH/Tillämpad termodynamik och kylteknik

    Författare :Camille Simondon; [2014]
    Nyckelord :Borehole Heat Exchanger; Ground Source Heat Pump; Distributed Thermal Response Test; Python; Evaluation Tool;

    Sammanfattning : Nowadays Ground Source Heat Pumps (GSHP) are widely used to provide heating and/or cooling as well as domestic hot water in commercial and residential buildings. The Swedish GSHPs market is the first one in the European Union with more than 378,000 units installed until 2010 according to the Swedish Heat Pump Association (SVEP). LÄS MER

  7. 20. Next generation high productivity submerged arc welding

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :MARKUS LANGENOJA; VINCENT ÖHRVALL KARLSSON; [2012]
    Nyckelord :;

    Sammanfattning : The task of designing concepts for the next generation of submerged arc welding heads was given by ESAB. ESAB is a global company manufacturing welding equipment for a wide span of industries and uses. In October 2011, ESAB introduced a new technology called Integrated Cold Electrode™, abbreviated and trademarked as ICE™. LÄS MER
